need to collect files in a folder and all its subfolders

Im tryng to load filenames to a list. The problem is that I cant seem to find a way to browse subfolders within a folder. I mean, if i wanted to add all files in the windows directory, the program would also add all files contained in all of the windows folder's subdirectories, and on all their respective subdirectories.

What do you mean by a list? Are you just trying to create an array or do you want to display the list of directories so that you can select from them? If the latter, you can use a DirListBox which will do all the hard work for you...

This has been answered by me several times in this forum, you can do a search to find it, I'd say: SUBFOLDER, but I'll do the work for ye ...
Thread:
http://www.vbforums.com/showthread.p...threadid=91531 (to get all subfolders using FSO)

Code:

---

Dim FSO As FileSystemObject
Dim fFolder As Folder
Dim fRoot As Folder

Private Sub Form_Load()
    Set FSO = New FileSystemObject
    ShowFolders ("C:\")
End Sub

Private Sub ShowFolders(Path As String)
    Set fRoot = FSO.GetFolder(Path)
    For Each fFolder In fRoot.SubFolders
        MsgBox fFolder.Name
        ShowFolders(fFolder.Path)
    Next
End Sub

---

All you have to do is throw in file capabilities.

Code:

---

Dim FSO As FileSystemObject
Dim fFolder As Folder
Dim fRoot As Folder
Dim fFile As File

Private Sub Form_Load()
    Set FSO = New FileSystemObject
    ShowFolders ("C:\")
End Sub

Private Sub ShowFolders(Path As String)
    Set fRoot = FSO.GetFolder(Path)
    For Each fFolder In fRoot.SubFolders
        MsgBox fFolder.Name
        GetFiles(Path)
        ShowFolders(fFolder.Path)
    Next
End Sub

Private Sub GetFiles(Path As String)
    Dim fSub As Folder
    Set fSub = FSO.GetFolder(Path)
    For Each fFile In fSub.Files
        MsgBox fFile.Name
    Next
End Sub

---

Now all you have to do is change the MsgBox commands to List1.AddItem commands.
You will need the microsoft scripting runtime added to your references or use the createobject function.

yeah im trying to load the names on a list so the user selects which files to process. I knew about the filesystemobject, but i coudn't figure out how to make it work with all subfolders. I'll give it a try sometime tonite . . . THANX A WHOLE LOT MAN!!!!

=)

Here is code using the API.

I've tested this code against using FSO and using the Dir function. This code is much faster than the other two methods.

Copy it into a class module. There is a function to return all
results in an array and one to populate a listbox. Let me know what you think.

well im really not very familiar with the API, so to me all that code looks rather complex. I'll give it a try though, and i'll try to figure it out. thanx
